I was just reading a recent research paper from the Communications of the ACM as titled “How intuitive is OOD”. Some concepts from the paper: recent research in cognitive psychology indicate that people do simple mistakes in their everyday activities because of intuitive thinking even in the area of their expertise.

Math as well as formal education teaches formal/systematic thinking that should override intuitive thinking. OOP designers are also sometimes biased by their intuitive (intuition based) thinking and may fail to identify classes, objects, and their relationships correctly. They think in terms of their intuition/intuitive knowledge (intuitive knowledge on what objects mean to them in real life and how they are used to think the relationships among objects) and sometimes they forget to use the formal knowledge that they have earned through education/OOD courses.

The point is: the issue is identified. Now OOP designers need to be careful about their intuition-based thinking and find ways to get rid of it (if there is any such issue with anyone). From: http://sitestree.com/?p=4846

Hibernate: A simple example

1. First, you need to create an xml file to specify the database parameters that you are going to use. Database parameters may include: the database driver, user name and password to access the database.
2. Then you should create a persistent class to represent the database table. One member variable for each table column.Also, you are required to write get and set methods for all of the member variable.
3. Then you need to write another XML file to map table columns to class variables.
4. Finally, you need to write the code to make use of the persistent class to store and/or retrieve data from the table.

Examples

1. XML file (hibernate.cfg.xml) to specify the database parameters:
   

   com.mysql.jdbc.Driver
   jdbc:mysql://localhost/hibernatetutorial
   root

   10
   true
   org.hibernate.dialect.MySQLDialect
   update
   

   I think you know how to write a class with get and set methods

   XML file to map table columns to class variables.
   

   SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

   session =sessionFactory.openSession();

   //Create new instance of Contact and set values in it by reading them from form object, Contact is the persistent class here

   System.out.println(“Inserting Record”);
   Contact contact = new Contact();
   contact.setFirstName(“XYZ”);
   session.flush();
   session.close();

What is Hibernate? What does it mean to J2EE developers
Hibernate is an open source free Java package that provides easy and efficient ways to deal with relational databases. Hibernate gives the abstraction that your databases contain just objects rather than tables. You manipulate objects to insert data or to get data from the database tables. You do not write or use SQL statements for the purpose. Though you need to map table columns to object variables.

Is Hibernate appropriate in all situations or for all?

No.
If you are already comfortable working with relational databases and know how to craft the perfect SQL query to interact with an enterprise database, Hibernate may not be the right way to go. You may better try to use iBATIS. In some situations, a full blown EJB architecture is more appropriate.
